I've personally noticed that I get more irritated/angry 4-5hrs after my meal. This is quite evident for me in the morning when I delay my breakfast. Hence I try to time my meals religiously. Though getting irritated/angry doesn't affect my "willpower" as I can still keep my emotions in check and prevent them from ebbing out. Coming back to the experiment, shouldn't the will power be benchmarked before testing for effects of glucose? Hypothetically, couldn't I get a study group of weak-willed people and enforce the WSJ article's premise as well as get a bunch of monks and refute it?
